Drives AutoCAD DWG automation over a negotiated transport (interactive COM or headless accoreconsole). Provides tools for inspecting drawings (bounded entity, layer, and layout metadata), creating new DWGs from templates, ensuring layers exist, and appending typed entities such as lines, circles, points, and text, plus status reporting on host discovery, transport, and active capabilities.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@dcc-mcp-autocad create a new drawing, ensure layer Walls exists, and add a circle at 10,10 radius 5"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
AutoCAD adapter for the DCC Model Context Protocol ecosystem — typed DWG automation for agents, portable-first.
dcc-mcp-autocad is the ecosystem's first portable-first adapter. Locating
the host never depends on a registered COM ProgID, so green/portable installs
work, and the headless accoreconsole.exe path keeps batch automation usable
even where COM is unavailable.
Two interchangeable transports implement one contract:
Transport | Host | Capabilities |
| interactive AutoCAD | live document, window handle, interactive selection, batch edit, plot |
|
| batch edit, plot |
The bridge negotiates the richest available transport at runtime and reports the resulting capability set.

When only the headless transport is usable, these capabilities are unavailable
and are declared by get_status rather than failing silently:
no live document session — drawings open and save per operation
no window handle — UI targeting is unavailable
no interactive selection — pass typed entity arguments instead
pip install dcc-mcp-autocad
# on Windows, for the interactive COM transport:
pip install "dcc-mcp-autocad[windows]"Verify the host:
dcc-mcp-autocad-doctor doctor --json
dcc-mcp-autocad-doctor verify --json --transport accoreconsoleResolution order — no step requires COM registration:
AUTOCAD_EXE environment variable
Registry install location
Known installation directories (C:\Program Files\Autodesk\AutoCAD <year>)
accoreconsole.exe is resolved as a sibling of acad.exe. COM ProgIDs are an
optional accelerator with a version-tolerant fallback chain
(AutoCAD.Application.25.1 → 25 → 24.3 → unversioned), never a prerequisite.
The bundled autocad-drawings skill exposes:
get_status — discovery, transport, and active capabilities
inspect_drawing — bounded entity, layer, and layout metadata
create_drawing — new DWG from a template
manage_layers — ensure layers exist
add_entities — append typed lines, circles, points, or text
Entity arguments are JSON data only; callers cannot supply source code.
An external bridge host: the adapter's Python runs outside AutoCAD and
drives it over the negotiated transport. AutoCAD ships no embedded Python, so
the host imposes no Python version constraint — only the shared
dcc-mcp-core >= 3.7 floor applies.
